Do spellcheckers exist that are aware of Markdown?

I would like to run a spellchecker over my articles before I publish them. I think aspell is ok, but it should not try to check code blocks: asdfasdfa adsfa sdfa text to check adsfasd f

a wild code block appeared!
    thisHas quiteOften() some strings.that should NOT get changed

and also inlined code should not get checked **Do command line based spellcheckers exist for Linux that are aware of Markdown and hence ignore code blocks?** I need to be able to run this in batch mode for multiple files. (Bonus points if you know one that really understands LaTeX - no, aspell -t does not completely work)
